Monitor Mount - Height Adjustable - Horizontal or Vertical Setup - Tool-less Assembly Customize your workspace like never before with this premium desk-mount dual monitor arm. It supports two VESA (75x75, 100x100) monitors, side-by-side or stacked. The full-motion articulating arms with spring-assisted height adjustment let you reposition your monitors with ease. Horizontal or Vertical Setup Create a dual-monitor setup to suit your needs, using the interchangeable arms with quick-connect assembly. In a horizontal setup, the dual-monitor mount supports two monitors from 12" to 30". It's ideal for numerous uses including graphic design, photo editing and many others. As a vertical monitor stand, the dual-monitor arm supports two monitors from 12" to 24". A stacked setup makes it easy to compare information on two screens without scrolling. Please note: To support two stacked 24" monitors, the height of each monitor (including the bezel around the display) cannot exceed 14" (35 cm). Full-Motion Articulating Arms The adjustable dual monitor arm offers a full range of motion on several axes, letting you tilt, pan and rotate. Switch from landscape to portrait viewing. Spring-Assisted Height Adjustment Raise or lower your monitors with one smooth motion, using the spring-assisted height adjustment. Adjust the tension to your own preference. Durable Construction With its steel and aluminum construction, the dual monitor mount supports a weight capacity of 19.8 lb. (9 kg) per arm. Tool-less Assembly The quick slide-and-click connections make the dual-monitor mount easy to assemble. Clamp the monitor mount to the side of your desk or table (using the pre-installed desk clamp) or attach it through a grommet hole. The TAA compliant ARMDUAL30 is backed by a 10-year StarTech.com warranty and free lifetime technical support.
